Around your water cooler or at lunch, have you heard anyone talking about SIP? Or maybe about SIP trunking? Have you wondered what it was all about, what it meant? Did you have any idea that you can actually get rich off of SIP?
Are you intrigued? I bet you are.
SIP stands for Session Initiation Protocol. This dry little TLA (three letter acronym) has become a standard in the telecommunications industry over the past few years. It’s now a protocol of first choice for making phone calls on a data network.
You might already know this technology as VoIP, or Voice Over Internet Protocol.
What, then, is SIP Trunking, and why is it important? A SIP Trunk is a logical phone wire that offers the same service that you would get from one physical copper phone line. The SIP trunk is provided by a provider of these services, of which there are many. They can then use your data line, whatever it might be (DSL, Cable Modem, T1, etc) to connect your phone lines to their network.
Structuring your data lines in this way has many advantages.
Discrete circuits will no longer be needed to deliver calls. They’ll be served up by the Internet, and not by copper wires. Therefore, painstaking maintenance of phone boxes, punch down blocks and aging equipment will no longer be needed. This will have the overall effect of making your domestic calling significantly more inexpensive. Furthermore, toll charges on long-distance calls are eliminated.
The same structure will apply to international calls as well. Gone are the days of having to set up a dedicated circuit from Osaka all the way to Dubuque. Now your calls will be broken up into packets. Some will travel one way, some another, but they’ll all end up in the right place at the right time. They will all get assembled properly so both ends of the call can hear each other properly and clear as a crystal. This was often not possible with circuit-switched lines, which were subject to damage and simple wear and tear.
Maintains Business Continuity
Using SIP helps you to maintain continuity of your business in the event of a natural disaster or other unforeseen circumstance. SIP makes that recovery more efficient and faster by using the distributed architecture of an IP network. What’s a distributed architecture? It’s a network that’s not concentrated in one place. If one area takes a big hit, it’s easier to work around that damaged area while it gets repaired. Typically, all SIP trunking features live at the SIP provider’s premises, and not where the customer is. So in case of an Act of God, it’s easy enough to redirect calls to a different corporate location that’s not affected.
Single IP network
SIP Trunking places all of your communications needs under one roof and in one location. This also means that you also have one point of contact, and one bill to deal with. You can pick DIDs from nearly any place in the country and attach them to your central PBX quickly and easily. It’s also extremely easy to manage calling features and your account as well, from any mobile device or even a web browser.
Call and Receive Calls from Non-VoIP Numbers
You might think that if you get SIP Trunking, then you would be limited to calling other people with similar equipment. Not so; not so at all. When you’re using SIP trunking equipment, you can call anyone you want, at any time you want, just as if you were using a PSTN network. You’re not limited in the least. In fact, when using SIP, the possibilities for calling are opened up even more! If you’re into communications or consider yourself a business leader, you owe it to yourself to look into this technology.
